Everyone is concerned about touching the center. That's not the part violated. The section that I think should has been used reads,
"Placing a hand or hands on a teammate or opponent to gain additional height to block or attempt to block an opponent’s kick. "
Notice the rusher puts his hands on teammates to be able to vault the center. The rule doesn't state the rusher has to block the kick at the apex of his jump for this to be a violation. It simply says you can't use fellow players in the process. That makes the attempt clearly illegal. In fact even if he missed the ball entirely it's still a penalty to use other players in the attempt.
